About FICON
Cisco MDS switches have a dynamic FC ID allocation scheme. When FICON is enabled or disabled on
a VSAN, all the ports are flapped to switch from the dynamic to static FC IDs and vice versa (see
Figure 22-4).

FICON Cascading
The Cisco MDS SAN-OS software allows multiple switches in a FICON network. To configure multiple
switches, you must enabled and configure fabric binding in that switch.
FICON VSAN Prerequisites
To ensure that a FICON VSAN is operationally up, be sure to verify the following requirements:
•Set the default zone to permit, if you are not using the zoning feature. See the “The Default Zone”
section on page 15-15.
•Enable in-order delivery on the VSAN.
•Enable (and if required, configure) fabric binding on the VSAN.
•Verify that conflicting persistent FC IDs do not exist in the switch.
•Verify that the configured domain ID and requested domain ID match.
•Add the CUP (area FE) to the zone, if you are using zoning.
If any of these requirements are not met, the FICON feature cannot be enabled.
Static Domain Port Address Last Byte
5 0x44 0
Static FC ID allocation for interface fc3/5 includes the
static domain ID (5), the port address (0x44), and the last byte value (0).
